Definitions

  • the vehicle structure further includes a reinforcement member 20 located in the hollow structural member 10 .
  • the reinforcement member 20 according to the first embodiment includes a foaming member F and a supporting member S that supports the foaming member F. More specifically, the vehicle structure according to the first embodiment includes a first reinforcement member 21 and a second reinforcement member 22 , each of which serves as the reinforcement member 20 .
  • the first reinforcement member 21 includes a single first foaming member F 1 located on one surface of the first supporting member S 1 .
  • the second reinforcement member 22 includes two second foaming members F 2 arranged to hold the second supporting member S 2 in between. In this manner, the number of foaming members F of a single reinforcement member 20 may be one or more.
  • the foaming body can be made of a polymeric material.
  • the foaming base material contains a base material, a blowing agent, and a cross-linking agent.
  • the base material includes, for example, synthetic resin, elastomer, and rubber.
  • the synthetic resin includes, for example, polyolefin, epoxy resin, phenolic resin, urethane resin, acrylic resin, styrene resin, and ethylene-vinyl acetate copolymer (EVA).
  • the blowing agent includes, for example, azodicarbonamide and dinitrosopentamethylenetetramine.
  • the cross-linking agent includes, for example, dimethylurea and dicyandiamide.
  • each of the two second foaming members F 2 is connected to the second panel portion P 2 and the third panel portion P 3 .
  • the subject to which the two second foaming members F 2 are connected may be changed as follows. For example, as shown in FIG. 3 , one of the second foaming members F 2 may be connected to the second panel portion P 2 , and the other one of the second foaming members F 2 may be connected to the third panel portion P 3 .
  • the first reinforcement member 21 includes two first foaming members F 1
  • one of the first foaming members F 1 may be connected to the first panel portion P 1
  • the other one of the first foaming members F 1 may be connected to the third panel portion P 3 .
  • the first reinforcement member 21 may include three or more first foaming members F 1 supported by the first supporting member S 1 .
  • the second reinforcement member 22 may include three or more second foaming members F 2 supported by the second supporting member S 2 .
  • the number of the first reinforcement members 21 may be one or more.
  • the number of the second reinforcement members 22 may be one or more.
  • the number of the third reinforcement members 23 may be one or more.
  • the vehicle structure may include a fourth reinforcement member in addition to the first, second, and third reinforcement members 21 , 22 , 23 .
  • the fourth reinforcement member includes, for example, a fourth foaming member connected only to the first panel portion P 1 of the first hollow structural portion 11 or connected only to the second panel portion P 2 of the second hollow structural portion 12 .
  • the hollow structural member 10 may be modified to a hollow structural member 10 including two first hollow structural portions 11 arranged along the first direction D 1 .
  • the two first hollow structural portions 11 and a single second hollow structural portion 12 are coupled to each other by the third hollow structural portion 13 .
  • the vehicle structure includes a first reinforcement member 21 connected to the first panel portion P 1 of one of the first hollow structural portions 11 and a first reinforcement member 21 connected to the first panel portion P 1 of the other one of the first hollow structural portions 11 .
  • One of the first reinforcement members 21 may be omitted.
